A distant quasar has revealed one of the most extreme ultraviolet outflows ever observed, providing new clues about the powerful interactions between supermassive black holes and their host galaxies. A supermassive black hole more than a billion times the mass of the Sun is blasting gas through space at such extraordinary speeds that astronomers are [...]Scientists found that aging may begin with a hidden cellular remodel that could help drive disease later in life. Thanks to advances in public health, people are living longer than ever before. However, many of those extra years are accompanied by chronic illnesses rather than good health. Aging is a normal part of life, but [...]Scientists have uncovered a potential nutritional link to chronic fatigue. Healthy adults with signs of vitamin B12 and folate deficiencies were more likely to experience fatigue or lower motivation. Chronic fatigue has become a common part of modern life. Many people struggle with long work hours, packed schedules, and persistent exhaustion that never seems to [...]Scientists caught a famous “sandwich” molecule in a rare hidden state, uncovering a long-missing step in its formation. For more than 70 years, metallocenes have been among the most important molecules in organometallic chemistry. These compounds feature a metal atom positioned between two carbon-based rings, creating a structure often described as a molecular sandwich. They [...]A new prototype takes mass spectrometry from analyzing a few molecules at a time to handling billions at once. Mass spectrometry is already a cornerstone technology for identifying what molecules are present in a sample and how much of each is there. However, most current instruments still examine molecules one at a time or in [...]Researchers have uncovered why a common and costly dental implant infection often resists antibiotics. Dental implants have helped tens of millions of people regain a full set of stable, functional teeth, something traditional dentures cannot provide. However, between 10% and 20% of implant recipients eventually develop peri-implantitis, a serious infection that damages the jawbone around [...]
A newly identified pest is raising concerns for North Carolina’s blueberry industry. What began as a mystery beneath North Carolina’s blueberry fields has now been traced to a surprising culprit: a giant root-feeding beetle never before confirmed attacking blueberries anywhere else in the United States. Researchers at North Carolina State University have identified the insect [...]A new study challenges the long-held idea that habits form only through slow, gradual repetition. What if your habits don’t form through countless repetitions over months or years? What if the brain can decide, almost instantly, that a behavior is no longer worth thinking about? That possibility is at the center of a new Johns [...]A new study shows that tau helps organize and preserve long-term memories, while abnormal tau may contribute to memory problems in Alzheimer’s disease by disrupting memory formation and recall. New research has revealed that tau, a protein closely linked to Alzheimer’s disease, is also essential for creating long-lasting memories. The findings could point to new [...]A newly identified prehistoric crocodile relative, Eosphorosuchus lacrimosa, was discovered alongside another croc species in New Mexico fossils dating back 210 million years. Around 210 million years ago, two crocodile relatives about the size of modern jackals stood together along a humid riverbank in what is now northern New Mexico. One of them, Hesperosuchus agilis, [...]Two new tool compounds may help scientists study TAOK proteins linked to Alzheimer’s disease and other neurological disorders. Alzheimer’s disease is the leading cause of dementia and affects more than seven million people in the United States. Some treatments can slow the disease, but most address symptoms rather than the root biology, and none can [...]Stanford researchers have developed a microscope that can show how nanostructures interact inside living cells at the highest resolution achieved so far. The view into living cells just got better. Stanford researchers have merged two microscopy methods to build a unique instrument that can capture cell structures interacting in real time at an unprecedented resolution [...]A new evolutionary analysis suggests that modern blood and immune cells may preserve a 700-million-year legacy inherited from ancient single-celled ancestors. Long before humans, dinosaurs, or even fish existed, ancient single-celled organisms may have already carried the genetic blueprint for one of the body’s most important systems: blood. A new study from Kyoto University suggests [...]Scientists discovered that fog droplets can host living bacteria that grow and help remove harmful pollutants from the atmosphere, revealing fog as a surprisingly active microbial environment. Every breath you take may contain microscopic hitchhikers floating through the atmosphere. Scientists have known for years that bacteria drift through clouds and air currents, but new research [...]Parents in rural, low-income households who maintained strong family routines reported fewer behavior problems and ADHD symptoms in their children. Starting elementary school is an important step for children, but the shift can be challenging. Some children experience separation anxiety, while others have difficulty adjusting to classroom rules and daily school structure. A Penn State-led [...]Scientists have discovered that the brain’s sensory systems play a much larger role in speech learning than previously believed. New research suggests that learning to speak a new language, or recovering speech after injury, relies more heavily on the brain’s sensory systems than on regions responsible for controlling movement. The findings, from researchers at McGill [...]
